     1. EXERCISE OF WARRANT.

     This Warrant may be exercised in full or in part at any time or from time
to time from the Issue Date until the Expiration Date by the Holder by surrender
of this Warrant and the subscription form annexed hereto (duly executed) by the
Holder, to the Company at its principal office, accompanied by payment, in cash
or by certified or official bank check payable to the order of the Company, in
the amount obtained by multiplying (a) the number of shares of Common Stock
designated by the Holder in the subscription form by (b) the Purchase Price then
in effect. Payment may also be made by delivery of shares of the Company's
Common Stock or Preferred Stock having an aggregate fair market value (as
determined in good faith by the Board of Directors) equal to the Purchase Price
on the date of exercise. On any partial exercise the Company at its expense will
forthwith issue and deliver to or upon the order of the Holder a new Warrant or
Warrants of like tenor, in the name of the Holder or as the Holder (upon payment
by the Holder of any applicable transfer taxes) may request, providing in the
aggregate on the face or faces thereof for the number of shares of Common Stock
for which such Warrant or Warrants may still be exercised.

                                       -2-



     2. DELIVERY OF STOCK CERTIFICATES ON EXERCISE. As soon as practicable after
the exercise of this Warrant, and in any event within ten days thereafter, the
Company at its expense (including the payment by it of any applicable issue or
stamp taxes) will cause to be issued in the name of and delivered to the Holder,
or as the Holder (upon payment by the Holder of any applicable transfer taxes)
may direct, a certificate or certificates for the number of fully paid and
nonassessable shares of Common Stock (or Other Securities) to which the Holder
shall be entitled on such exercise, in such denominations as may be requested by
the Holder, plus, in lieu of any fractional share to which the Holder would
otherwise be entitled, cash equal to such fraction multiplied by the then
current market value (as determined in good faith by the Board of Directors), of
one full share (less such fractional exercise price with respect to such
shares), together with any other stock or other securities and property
(including cash, where applicable) to which the Holder is entitled upon such
exercise pursuant to Section 1 or otherwise.

     3. ADJUSTMENT FOR DIVIDENDS IN OTHER STOCK OR PROPERTY; RECLASSIFICATION.
In case at any time or from time to time the holders of Common Stock (or Other
Securities) shall have received, or (on or after the record date fixed for the
determination of shareholders eligible to receive) shall have become entitled to
receive, without payment therefor,

          (a) other or additional stock or other securities or property (other
     than cash) by way of dividend, or

          (b) any cash (excluding cash dividends payable solely out of earnings
     or earned surplus of the Company), or

          (c) other or additional stock or other securities or property
     (including cash) by way of spin-off, split-up, reclassification,
     recapitalization, combination of shares or similar corporate rearrangement,

other than additional shares of Common Stock (or Other Securities) issued as a
stock dividend or in a stock-split (adjustments in respect of which are provided
for in Section 5), then and in each such case the Holder, on the exercise hereof
as provided in Section 1, shall be entitled to receive the amount of stock and
other securities and property (including cash in the cases referred to in
subsections (b) and (c) of this Section 3) which the Holder would hold on the
date of such exercise if on the Issue Date the Holder had been the holder of
record of the number of shares of Common Stock called for on the face of this
Warrant and had thereafter, during the period from the Issue Date to and
including the date of such exercise, retained such shares and all such other or
additional stock and other securities and property (including cash in the cases
referred to in subsections (b) and (c) of this Section 3) receivable by him as
aforesaid during such period, giving effect to all adjustments called for during
such period by Section 4.

                                       -3-



     4. ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION, MERGER.

     (a) In case at any time or from time to time, the Company shall (i) effect
a reorganization or (ii) consolidate with or merge into any other person, then,
in each such case, the Holder, on the exercise hereof as provided in Section 1
at any time after the consummation of such reorganization, consolidation or
merger, as the case may be, shall receive, in lieu of the Common Stock (or Other
Securities) issuable on such exercise prior to such consummation or such
effective date, the stock and other securities and property (including cash) to
which the Holder would have been entitled upon such consummation as the case may
be, if the Holder had so exercised this warrant, immediately prior thereto, all
subject to further adjustment thereafter as provided in Sections 3 and 5.

     (b) Upon any reorganization, consolidation or merger referred to in this
Section 4 (except as set forth in the second parenthetical in Section 6(c)),
this Warrant shall continue in full force and effect and the terms hereof shall
be applicable to the shares of stock and other securities and property
receivable on the exercise of this Warrant after the consummation of such
reorganization, consolidation or merger, as the case may be, and shall be
binding upon the issuer of any such stock or other securities.

     5. ADJUSTMENT FOR EXTRAORDINARY EVENTS. In the event that the Company shall
(a) issue additional shares of the Common stock as a dividend or other
distribution on outstanding Common stock, (b) subdivide or reclassify its
outstanding shares of Common Stock, or (c) combine its outstanding shares of
Common stock into a smaller number of shares of Common Stock, then, in each such
event, the Purchase Price shall, simultaneously with the happening of such
event, be adjusted by multiplying the then Purchase Price by a fraction, the
numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to such event and the denominator of which shall be the number
of shares of Common Stock outstanding immediately after such event, and the
product so obtained shall thereafter be the Purchase Price then in effect. The
Purchase Price, as so adjusted, shall be readjusted in the same manner upon the
happening of any successive event or events described herein in this Section 5.
The Holder shall thereafter, on the exercise hereof as provided in Section 1, be
entitled to receive that number of shares of Common Stock determined by
multiplying the number of shares of Common Stock which would be issuable on such
exercise as of immediately prior to such issuance by a fraction of which (i) the
numerator is the Purchase Price in effect immediately prior to such issuance and
(ii) the denominator is the Purchase Price in effect on the date of such
exercise.

     6. NO IMPAIRMENT. The Company will not, by amendment of its Certificate of
Incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, or any other similar voluntary action, avoid or seek to
avoid the observance or performance of any of the terms of this Warrant, but
will at all times in good faith assist in the carrying out of all such terms and
in the taking of all such action as may be necessary or appropriate in order to
protect the rights of the Holder

                                       -4-



against impairment due to such event. Without limiting the generality of
the foregoing, the Company (a) will not increase the par value of any shares of
stock receivable on the exercise of the Warrant above the amount payable
therefor on such exercise, (b) will take all action that may be necessary or
appropriate in order that the Company may validly and legally issue fully paid
and nonassessable shares of stock, free from all taxes, liens and charges with
respect to the issue thereof, on the exercise of all of the Warrants from time
to time outstanding, and (c) will not consolidate with or merge into any other
person or permit any such person to consolidate with or merge into the Company
(if the Company is not the surviving person), unless such other person shall,
pursuant to Section 5 hereof, expressly assume in writing and will be bound by
all the terms of this Warrant (except where the consideration with respect to
such merger is cash or publicly-listed securities).

     7. CHIEF FINANCIAL OFFICERS' CERTIFICATE AS TO ADJUSTMENTS. In each case of
any adjustment or readjustment in the shares of Common Stock (or Other
Securities) issuable on the exercise of the Warrants, the Chief Financial
Officer of the Company will promptly compute such adjustment or readjustment in
accordance with the terms of this Warrant and prepare a certificate setting
forth such adjustment or readjustment, the Purchase Price resulting therefrom
and the increase or decrease, if any, or the number of shares purchasable at
such price upon exercise of the Warrant, and showing in detail the facts and
computation upon which such adjustment or readjustment is based. The Company
will forthwith mail a copy of each such certificate to each registered holder of
this Warrant, and will, on the written request at any time of the Holder,
furnish to the Holder a like certificate setting forth the Purchase Price at the
time in effect and showing how it was calculated.

     8. NOTICES OF RECORD DATE. In the event of

          (a) any taking by the Company of a record of the holders of any class
     of securities for the purpose of determining the holders thereof who are
     entitled to receive any dividend on, or any right to subscribe for,
     purchase or otherwise acquire any shares of stock of any class or any other
     securities or property, or to receive any other right, or

          (b) any capital reorganization of the Company, any reclassification or
     recapitalization of the capital stock of the Company or any transfer of all
     or substantially all the assets of the Company to, or consolidation or
     merger of the Company with or into, any other person, or

          (c) any voluntary or involuntary dissolution, liquidation or
     winding-up of the Company,

then and in each such event the Company will mail or deliver or cause to be
mailed or delivered to the registered holder of this Warrant a notice specifying
(i) the date on which any such record is to be taken for the purpose of such
dividend, distribution or

                                       -5-



right, and stating the amount and character of such dividend, distribution or
right, (ii) the date on which any such reorganization, reclassification,
recapitalization, transfer, consolidation, merger, dissolution, liquidation or
winding-up is to take place, and the time, if any is to be fixed, as of which
the holders of record of Common Stock (or Other Securities) shall be entitled to
exchange their shares of Common Stock (or Other Securities) for securities or
other property deliverable on such reorganization, reclassification,
recapitalization, transfer, consolidation, merger, dissolution, liquidation or
winding-up, and (iii) the amount and character of any stock or other securities,
or rights or options with respect thereto, proposed to be issued or granted, the
date of such proposed issue or grant and the persons or class of persons to whom
such proposed issue or grant is to be offered or made. Such notice shall also
state that the action in question or the record date is subject to the
effectiveness of a registration statement under the Securities Act of 1933, as
amended (the "SECURITIES ACT"), or a favorable vote of stockholders if either is
required. Such notice shall be mailed at least 20 days prior to the date
specified in such notice on which any such action is to be taken or the record
date, whichever is earlier.

     9. RESERVATION OF STOCK ISSUABLE ON EXERCISE OF WARRANTS. The Company will
at all times reserve and keep available, solely for issuance and delivery on the
exercise of this Warrant, all shares of Common Stock (or Other Securities) from
time to time issuable on the exercise of this Warrant.

     10. TRANSFER OF WARRANT. Subject to applicable federal and state securities
laws, the transfer of this Warrant and all rights hereunder, in whole or in

of this Warrant properly endorsed. Each taker and holder of this Warrant, by
taking or holding the same, consents and agrees that this Warrant, when endorsed
in blank, shall be deemed negotiable, and that the holder hereof, when this

register for the Warrants, in which the Company shall record the name and
address of the person in whose name a Warrant has been issued, as well as the
name and address of each transferee and each prior owner of such Warrant.

                                       -6-



     12. EXCHANGE OF WARRANTS. This Warrant is exchangeable, upon the surrender
hereof by the Holder at the office or agency of the Company referred to in
Section 11, for one or more new Warrants of like tenor representing in the
aggregate the right to subscribe for and purchase the number of shares of Common
Stock which may be subscribed for and purchased hereunder, each of such new
Warrants to represent the right to subscribe for and purchase such number of
shares as shall be designated by the Holder at the time of such surrender.

     13. REPLACEMENT OF WARRANTS. Upon receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of any such loss, theft or destruction of this
Warrant, on delivery of an indemnity agreement or security reasonably
satisfactory in form and amount to the Company or, in the case of any such
mutilation, on surrender and cancellation of such Warrant, the Company at its
expense will execute and deliver, in lieu thereof, a new Warrant of like tenor;
provided, however, if the registered holder of this Warrant is the original
holder of this Warrant on the Issue Date, its nominee, or any of its officers,
directors or general partners, and this Warrant is lost, stolen or destroyed,
the affidavit of the President, a director or a general partner of the
registered holder setting forth the circumstances with respect to such loss,
theft or destruction shall be accepted as satisfactory evidence thereof, and no
indemnity bond or other security shall be required as a condition to the
execution and delivery by the Company of a new Warrant in replacement of such
lost, stolen or destroyed Warrant other than the registered holder's written
agreement to indemnify the Company.

     14. WARRANT AGENT. The Company may, by written notice to the registered
holder of this Warrant, appoint an agent having an office in the United States,
for the purpose of issuing Common Stock (or Other Securities) on the exercise of
the Warrant pursuant to Section 1, exchanging this Warrant pursuant to Section
12, and replacing this Warrant pursuant to Section 13, or any of the foregoing,
and thereafter any such issuance, exchange or replacement, as the case may be,
shall be made at such office by such agent.

     15. REGISTRATION RIGHTS. The Warrant Shares shall have registration rights
in accordance with the terms and provisions of that certain Registration Rights
Agreement dated as of May ___, 1996, which agreement shall be deemed
incorporated into this Warrant.

     16. REMEDIES. The Company stipulates that the remedies at law of the Holder
in the event of any default or threatened default by the Company in the
performance of or compliance with any of the terms of this Warrant are not and
will not be adequate, and that such terms may be specifically enforced by a
decree for the specific performance of any agreement contained herein or by an
injunction against a violation of any of the terms hereof or otherwise.

                                       -7-



     17. CLOSING OF BOOKS. The Company will at no time close its transfer books
against the transfer of any Warrant or of any shares of Common Stock issued or
issuable upon the exercise of any Warrant in any manner which interferes with
the timely exercise of this Warrant.

     18. NO RIGHTS OR LIABILITIES AS A STOCKHOLDER. This warrant shall not
entitle the Holder to any voting rights or other rights as a stockholder of the
Company. No provision of this Warrant, in the absence of affirmative action by
the Holder to purchase Common Stock, and no mere enumeration herein of the
rights or privileges of the Holder, shall give rise to any liability of the
Holder for the Purchase Price or as a stockholder of the Company, whether such
liability is asserted by the Company or by creditors of the Company.

     19. NOTICES. All notices and other communications from the Company to the
registered holder of this Warrant shall be mailed by first class registered or
certified mail, postage prepaid, or delivered by a nationally-recognized
overnight courier service, at the address of the Holder as shown on the books of
the Company or such other address as may have been furnished to the Company in
writing by the Holder.

     20. INVESTMENT REPRESENTATIONS. The Holder (and each subsequent Holder by
accepting this Warrant) represents to the Company that this Warrant is being
acquired for the Holder's own account and for the purpose of investment and not
with a view to, or in connection with, the resale, transfer or other
distribution thereof, nor with any present intention of reselling, transferring
or otherwise distributing the Warrant or the Common Stock issuable upon exercise
of the Warrant. The Holder acknowledges that the Holder has been afforded the
opportunity to meet with the management of the Company and to ask questions of,
and receive answers from, such management and the Company's counsel about the
business and affairs of the Company and concerning the terms and conditions of
the offering of this Warrant, and to obtain any additional information, to the
extent that the Company possessed such information or could acquire it without
unreasonable effort or expense, necessary to verify the accuracy of the
information otherwise obtained by or furnished to the Holder in connection with
the offering of this Warrant. The Holder agrees that the Company has furnished
to the Holder all information which the Holder considered necessary to form a
decision concerning the purchase of this Warrant, and no valid request to the
Company by the Holder for information of any kind about the Company has been
refused or denied by the Company or remains unfulfilled as of the date hereof.
The Holder asserts that it may be considered to be a sophisticated investor, is
familiar with the risks inherent in speculative investments such as in the
Company, has such knowledge and experience in financial business matters that it
is capable of evaluating the merits and risks of the investment in this Warrant
and the Common Stock issuable upon exercise of the Warrant, and is able to bear
the economic risk of the investment. The Holder (and each subsequent Holder by
accepting this Warrant) also represents and warrants that

                                       -8-



it is an "accredited investor" within the meaning of Regulation D promulgated
under the Securities Act.

     21. MISCELLANEOUS. This Warrant and any term hereof may be changed, waived,
discharged or terminated only by an instrument in writing signed by the party
against which enforcement of such change, waiver, discharge or termination is
sought. This Warrant shall be governed by and construed in accordance with the
general corporate laws of the State of Delaware and the internal domestic laws
of the State of New York. The headings in this Warrant are for purposes of
reference only, and shall not limit or otherwise affect any of the terms hereof.
The invalidity or unenforceability of any provision hereof shall in no way
affect the validity or enforceability of any other provision.
